Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $386 of the $604 with a category attached, or 63.9%. Every reported general payment came from a single manufacturer, Novartis. That places this record below the midpoint for cardiovascular disease clinicians in MO, where the typical reported total is $1,720.
Across 3 payments — averaging $201.38 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novartis$604
Across 13 payments — averaging $65,606 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Novartis$853K
What the payments were for
- Travel & lodging$38664%

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Novartis | 3 | $604 |
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
- LEQVIO$511
How this compares
$604 in reported general payments places this provider in the 30th percentile of 391 cardiovascular disease providers in Missouri.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
